Mods are a system meant to allow for varied and interesting mobile suit designs and character progression in the RPG. They are paid for with negative modifiers to your repair/replace rolls, amount varying on the usefulness of that specific mod. Sometimes, additional costs may apply. Do note that, if a mod has any non listed effect that is up to the player's creativity and discretion, it will be subject to staff approval.

The mods allowed for the E-1 [Chief Petty Officer] Rank are the following:

Nonstandard Extra WeaponryRepair/Replace Modifier: [-5]This mod allows pilots to customize their mobile suits with weaponry from different mobile suit models in their faction, and in exceptionally rare cases, with weapons from the opposite faction, although one might have to be lucky enough to salvage it from a battlefield. Same as the standard extra weapons mod, one may take this mod as many times as they want at their discretion, although it might result in low repair/replace rolls.
